Scope of Use

The JESANI Door Channel is suitable for use to contain accidental overflow from sanitary fixtures or sanitary appliances to meet NZBC Clause E3.3.2.

Overflow from:

  • Baths
  • Showers
  • Toilets
  • Vanities
  • Washing Machines
  • Dishwashers
  • Plumbed Fridges

The channel is installed along the threshold of interior doorways between wet and dry areas within the home/apartment/unit/holiday home, thus allowing the floor waste position to be located where water always finds its way out.  

Suitable for standard door lengths, and in custom sizes:

  • 40mm width trough
  • 38mm threaded outlet
  • 2 bar grill
  • Timber or concrete substrate
  • To suit various floor coverings, such as carpet to tile, and can accommodate underfloor heating

The Door Channel can also be classed as an Emergency Overflow, which allows an alternative option for the normal plumbing system.

Other Performance Attributes
  • BRANZ Appraisal 934
  • LIFEMARK product approved
  • Grade 304, 1.5mm thick stainless steel


The serviceable life of JESANI Shower and Door Channels, when subjected to normal conditions of environment and use, is expected to be compatible with the waterproofing membrane and floor finishes to which they are fitted.


Cleaning care of the stainless steel channel:

  • Avoid carbon steel brushes or steel wool and abrasive detergents; the brushes and wool may leave particles embedded on the surface which can lead to rusting, and abrasive cleaners could introduce the possibility of scratching the surface
  • Clean warm water and wipe are the simplest and safest method, followed by a clean water rinse and dry wipe. Stainless steels thrive with frequent cleaning
  • Periodically allow a cup of clean water to flow down the drain to keep it clear of dust/lint buildup
